Fair, but how would it look if you had some filters and reduces thrown in the middle?

In my F# file of 300 lines[1], I do this chaining over 20 times in various functions. Would you really want to write the Python code your way every time, or wouldn't you prefer a simpler syntax? People generally don't do it your way often because it has a higher mental burden than it does with the simple syntax in F# and other languages. I don't do it 20 times because of an obsession, but because it's natural.

[1] Line count is seriously inflated due to my habit of chaining across multiple lines as in my example above.
